The maximalist wing of crime fiction criticism has long held that the standard canon – Godwin, Poe, Collins, Conan Doyle, Christie and Sayers, Hammett and Chandler and so on – is too narrow and restrictive, and that pretty much anything with a crime in it – Hamlet, Bleak House, Crime and Punishment, Sanctuary, The Great Gatsby – should be recruited (or conscripted).
As well as stretching the boundaries of the genre to an unwieldy and unenlightening extent, this approach has always seemed to evince a certain cultural cringe, as if conceding that much of the genre is far from first rate and that its reputation needs bolstering by more conventionally respectable authors.
